Blackrock Gold Corp (CVE:BRC) has unveiled plans for an initial 7,000 metre drill campaign at its Tonopah West project at the famous Walker Lane trend in Nevada, earmarked to begin in June this year.
The previously worked Tonopah silver district produced 174 million ounces of silver and 1.8 million ounces of gold, while Blackrock's ground yielded 2.1 million tonnes of total Tonopah gold and silver production, the firm noted.
In recent months, Blackrock has been reviewing historic underground mining maps and assay data and consolidating other data to prioritize drill targets.
"Due to the prolonged fractured nature of the claims that make up what was known as the "Queen of the Silver Camps", one of the most significant high-grade mining districts in Nevada has been completely overlooked for decades," said Andrew Pollard, CEO of Blackrock in a statement.
"Our initial program is targeting low-hanging exploration fruit, picking up right where past miners left off, with well-defined veins that were up to 24m thick when operations ceased. We've outlined a large program as all of the targets we've compiled are priority and as we'll be using RC drilling, we'll be able to work quickly and cost effectively as we aim to bring attention back to this storied district," he added.
Five holes, totalling 2,750 metres (m), are proposed for the northern portion of the property at the Victor shaft, where the potential target ranges from 0.5 million to 1 million tonnes averaging 15 to 20 grams per ton (g/t) gold and gold equivalent, said Blackrock.
Another five holes, totalling 2,350m, will target near the KcKane shaft, where three veins were mined from the 1,200m to the 1,880m level. An area with potential ranging from 1 million to 3 million tonnes averaging 10 to 15 g/t gold and gold equivalent is the target.
A discovery was made using RC drilling in 1997, the firm noted, and follow-up drilling, over two decades later, cut two 1.5m zones grading 9.7 g/t gold, 715 g/t silver and 4.6 g/t gold, 401 g/t silver.
An initial program of four holes totalling 1,185m is planned at this zone, which is within the same stratigraphic package as the Ohio vein, located 1.5 kilometres (km) to the east, added the firm.
Finally, three holes totalling 750m are planned adjacent to the southeast portion of the property where the flat-lying Ohio vein was mined from the Ohio shaft.
Notably, because the bulk of the firm's land holdings are comprised of patented lands, no drill permitting is required for disturbance less than 5 acres, the firm said.
Tonopah West is a significant landholding within the historic district, comprising 97 patented and 17 unpatented lode mining claims
